^ PREFACE. 



inj^s. I am particularly indebted to Mr. .\le.\. Ki;er. I have 

 also to thank my friend, Dr. \\'. L. Williams. Professor of 

 Surgery in the New York State Veterinary College, for his 

 valuable suggestions as to the origin of teratoniata of the 

 mastoid region, and my brother Professor, Edw. Alerillat, 

 for his many original ideas which are entered throughout 

 the text with but a single credit, viz., the operation for clos- 

 ing skull perforations. 



With a full knowledge that the manuscript would crum- 

 ble from the assault of a literary critic, I forthwith apologize 

 to the censors of English veterinary literature. 



L. A. AlERILLAT.
